SELF-CLEARING ORE-POCKET.

Specification of Letters Patent.

Application filed luly 30, 1314 Serial No. 854,134.

To all whom it may-concern:

Be it known that I, LELAND CLAPPER, a citizen of the United States, and resident of Two Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Self- Clearing Ore-Pockets, of which the-following is a specification. 1

In the construction of ore docks which volves a chute of the same width at the top. If two or more doors are used the cost of construction is increased per bin, and in addition, the post or support between the door openings interferes with the flow of ore. To avoid these objections to one wide door or two or more narrower doors, it has been the practice to contract orhopper the disanduse one door of a convenient size at the center. The objection found in practice to this invention is that the ore tends to arch inasmuch as'the hopper construction on each. side forms an abutment or heel, for the arch.

ing broken away; Fig. 2 is a the constructions used hitherto, I propose the simple expedient of hopperingor contracting the bin upon one side only, leaving the other side straight, thus .obtaining one opening of a workable size and preventing the arching of the ore, asit is well known that an arch demands two abutments. In practice I have found that ore bins so constructed discharge theore much; more freely than thosehoppered on two sides and having the door in the middle. he invention will be stood by reference to drawings, wherein,

Figure 1 is a perspective view of a bin constructed in accordance with my invention, a portion of the front wall'thereof besection on the line 2'-2, of Fig. 3, and, Fig. 3 is a section on the line'33 of Fig. 2.

Referring more particularly to the drawings it will be seen that the bin may consist To avoid all the objectionable features of more readily underthe accompanying "ternally of the bin is a 'the side wall of a vertical wall 10, afront wall 11,- pro- Patented Feb. 15,1916...

vided with an opening 12, of less width than the width of the bin. A floor 13, is pro.- vided, this floor sloping downwardly and outwardly as is customary. Located in-' deflector, having two angles of inclination. The portion 14:, thereof is secured to the floor 13, and extends from theside wall 15 to the edge of'the discharge vopening 12, directing materials I toward such opening'in line'with their flow.

The portion 16, of the deflector extends from the side wall'15, to the upper edge of the deflector 14 and directs materials away from toward the opening.

By th the materials cannot arch over'the opening is construction it will be seen that.

as no support is provided on the side wall 10.

Bins so constructed readily clear themselves and the door opening may be of a convenient .size.

Obviously the construction is capable of considerable modification and such modifications as are with-in the scope of my claims I consider within the spirit of my invention. I claim 1. In a bin, a floor, opening extending over a portion only of the width of the bin, said floor being downwardly and outwardly inclined toward said the combination of walls and 'opening and of restricted area at a point contiguous to the opening, and a deflector located in the bin, said deflector having a double angle of inclination, whereby materials are directed toward the restricted discharge opening in substantially horizontal and vertical directions, substantially as described. I

2. In a bin, the combination of walls and a sloping floor, one of the side walls extendthe front wall having a discharge ing substantially vertically, the front wall I being provided a width less than the width of the bin, one edge of said opening substantially coinciding with said vertical wall; and an internal deflector for directing the materials to said opening, substantially as described.

' In a bin, the combination of walls and a sloping floor, one of the side walls extending substantially vertically, the front Wall being provided with a discharge opening of a width less than the width of the bin, one edge of said opening substantially coinciding with said vertical wall, and an internal deflector arranged at an angle to the, angle with a discharge opening of i of inclination of the floor and adapted to direct materials to said opening, substantially as described.

4. A bin having h vertical Side Wall, an inclined side Wall, a sloping floor, anda front wall provided with an opening of a,

frontand side wall extending substantially "ertically, said. front Wall being provided avith a discharge opening located with one Gopies of this patent may be obtained for five cents each; by addressing the Commissioner of Patents.
